CHARLES nLrREn lANDERS,,0N RAND, 0E N'EUss, GERMANY, nssIeNoR To INTER-NATIoNnL HARVESTER COMPANY or NEW JERSEY, a CORPORATION or NEW JERSEY.

To @ZZ 'whom it may concern: i

Be it known that I, CHARLES A. A. RAND, a` citizen of the United States,residing at Neuss, Rhineland, Germany,` haveinvented certain new anduseful Improvements in Tongue-Trucks, of which the following is a full,clear, and eXact specification.

Myinvention relates to tongue trucks, and especially to those used inconnection with mowers, harvesters, tillage implements or the like, andhaving a stub tongue as a part of the equipment.

The object ofmy invention is to `provide a construction of truck wherebythe draft connections between the truck and the device connected theretoaredirected in a manner to eliminate any tendency of the draft power tocause the operative partsy of the trailing device, as the cuttingapparatus of a mowing machine, to rise yfrom the ground during theoperation of the machine. n

l attain this object by means of mechanism, one embodiment of which isillustratedy in the accompanying drawing, in whichl Figure 1 is a topplan view of a tongue truck embodying my Yinvention and operativelyconnected with the stub tongue of a mowing machine; l Fig. 2 is asidelelevation of part of Fig. 1;

Fig. 8 is a front elevation ofthe truck along line AB as shown in Fig.1;

Fig. l is a cross section of partv of the draft mechanism as seen alongline C-D of Fig. 1.

Referring to the drawings, wherein the same reference numerals designatelike parts throughout the severalviews, 1 represents the main frame of akmowing machine; 2 the main driving shaft having carrying wheels 3 uponits opposite ends; 4; a stub tongue member having its rear ends securedto the main frame; 5 coupling barv having its stubbleward end``pivotally connected with the main frame in a manner permitting itsopposite end torise and fall in a vertical v plane in a. common Way; 6 acoupling yoke carried by thegrassward-end of the coupling bar andadapted to'rock `about its axis; 7 a diagonally disposed push bar havingone end connected with `the igrassward end ofthe ccuplingbar beyond theyoke 6 and its opposite endpivotally connected with the main frame inrear of the pivotal connection there with of the coupling bar 5; 8 aninner shoe roNGuE-rRUoK.

pivotally connected with the yoke 6, the axial line of its pivotalconnection `being in the direction ofthe line of draft of the machine; 9a finger' bar secured to theshoe; 10

a sickle carried by the finger bar; and 11 a bolts 17. The aXle membersare provided ,v

Vwith vertically disposed openings atv their opposite ends that formbearings for rocking wheel supporting shafts 18 having integraltherewith laterally turned arms 19 at their lower ends upon which arejournaled` truck wheels 20, and 21 represents forwardly diverging crankarms at the upper ends of the shafts having vertically disposed portions22 at their free ends to which are pivotally connected the rear ends ofwheel controlling bars 23. 24 represents a bracket member having avertically disposedsleeve 25 at its rear end whereby it is pivot-allyconnected with the axle members by means of a shaft 26 supported at itsupper end by means of a strap 27 secured to the stub tongue L of themachine. Y28 represents forwardly extending truck tongue members disposed in parallel relation, having their rear ends secured to oppositesides of the bracket member 24 and their front ends Vpivotally connectedwith opposite sides of a box niember 29 by means of a transverse bolt 30received by a transverse opening in the rear end of a draft tongue 31.The opposite sides of the box member 29 are provided with` laterallyextending ear members 32 spaced apart vertically` andy having open.-ings thereinthat receive a rocking draft member 33 provided with alaterally extend ing crank arm 34e at-its upper end and hav-` ing thefrontends of the wheel controlling bars 23 pivotally connected with itslower end. 35 represents a draft evener carried i that ris connectedwith theooupling bar Y5 of Vthe mower .by means of a draft bar 39 andlink 40 adapted to turn about the aXisof the oouplingbar. f Y l Vrheconstruction ofthe truck-is Isubstantially the same as .that shovvn'invan earlier patent to me issuedJ une 13, -l9ll,and.h av ing No. 994,787.Its fimctionof'guidlng and supporting the stubtongue is practically thesameftheessentialelements ofthe improvement being the draft connectionsbetiveen'the evener and the machine vvhereby the draft force istransmitted directly from the evener tothe couplingibar inalinesubstantially parallel iviththe surface ofthe `ground and inthesame -horizontalplane `as thelpoint of connection ivithathe vcouplingbar, thereby eliminating Vany tendency of thedraftrpovver to 'raise thecouplingframe` from the gronnd-and transferringl theV draft fromthefstub tongue of? the machine, as in myz patent notedfabove, :directlyto its coupling frame. l
